In this paper, the use of the recycled concrete aggregate (RCA) material in the performance of granular column construction is investigated through laboratory model tests. In the study, firstly, geotechnical properties of RCA material are investigated and some basic tests including particle size distribution, permeability, Los Angeles abrasion test, water absorption, specific gravity, triaxial test and direct shear test are conducted in order to characterize the RCA material. Following these tests, a series of laboratory model tests are carried out by using RCA and NA (natural aggregate) as a granular column material in soft soil deposits having different undrained shear strength. At the end of the model tests, it is concluded that reuse of recycled concrete aggregate can be considered in the construction of granular columns and play an important role in sustainable geotechnical design.
